• Potential data extraction from the database
• Possible disruption of database operations
• Need for verification of plugin version and exposure
• Priority for remediation and monitoring

Technical summary

The InfiniteWP Client plugin for WordPress is vulnerable to SQL Injection via the get_comments action in versions up to, and including, 1.13.9. This is due to insufficient escaping on array-key names supplied in the JSON request body before use in a SQL statement. The request body is read from php://input and JSON-decoded, bypassing wp_magic_quotes(). Authenticated attackers with administrator-level access can append additional SQL queries to extract sensitive information from the database. The vulnerability allows potential data extraction and disruption of database operations.

• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
